Rheology

Definition - What does Rheology mean?

Rheology is a branch of physics that deals with the study of the flow of liquid matter and the deformation of solid materials. Rheology considers the non-Newtonian fluids that remains viscous or in a semi-solid state and the deformation of solids during the application of a certain amount of force.

Corrosionpedia explains Rheology

Some examples of rheological measurement include:

Visocity profiling of non-Newtonian fluids that changes their shape and flow when a force is applied to it

Stabilizing the dispersion rate of a non-Newtonian fluid

Determining the thixotropy of paints and coatings

Determining the complete curing of particular paints and coatings so as to understand their bonding strength

A rheometer is a device used to measure fluid flow and solid deformation. When a viscous fluid or a semi-solid state fluid such as a slurry or fluid suspension flows due to an applied force, a rheometer measures the flow or the movement of this semi-solid state fluid and the amount of deformation it undergoes.
